You need to solve this equation for x: ax−7=26
Which would be the best first step you could make to solve the equation?
(1 point)
Responses
divide ax by a and 26 by a
subtract 7 from the left side of the equation
Combine ax - 7 to get -7x
add 7 to both sides of the equation
The best first step to solve the equation ax - 7 = 26 would be to add 7 to both sides of the equation.
Fill in the blanks to follow the steps in solving the equation: 5x−12−6x=−10x+7−1
5x−12−6x=−10x+7−1
Step 1: Combine like terms Response area,_______________
Step 2: Get x-terms on same side of equation Response area _______________
Step 3: Get constants on same side of equation Response area________________
Step 4: Get the x by itself by using the inverse operation Response area______________
Step 1: Combine like terms
5x - 12 - 6x = -10x + 7 - 1
Step 2: Get x-terms on same side of equation
5x - 6x + 10x = 7 - 1 + 12
Step 3: Get constants on same side of equation
9x = 18
Step 4: Get the x by itself by using the inverse operation
x = 2

The number of x's on both sides of the equation is different a≠b
The number of x's is the same on both sides of the equation, and the constant is different a=b, c1≠c2
The number of x's is the same on both sides of the equation and the constant is also the same a=b, c1=c2
The number of x's is the same on both sides of the equation, and the constant is different a=b, c1≠c2
The number of x's on both sides of the equation is different a≠b
The number of x's on both sides of the equation is different a≠b
number of solutions
The number of x's on both sides of the equation is different a≠b
The equation a≠b, where the number of x's on both sides of the equation is different, will have exactly one solution.
