To solve this system of equations, you can use either the substitution method or the elimination method. I will walk you through the elimination method step-by-step:
Step 1: Multiply the first equation by 4 and the second equation by -1, so that the coefficients of x in both equations will cancel each other out when added together.
-4x + 24y = 52 (equation 1 multiplied by 4)
-4x + 10y = 10 (equation 2 multiplied by -1)
Step 2: Add the two equations together, canceling out the x terms:
-4x + 24y + (-4x + 10y) = 52 + 10
Simplifying the equation:
14y = 62
Step 3: Divide both sides of the equation by 14 to solve for y:
y = 62/14
y = 4.42857 (rounded to 5 decimal places)
Step 4: Substitute the value of y (4.42857) into either of the original equations to find the value of x. Let's use the first equation:
-x + 6(4.42857) = 13
Simplify the equation:
-x + 26.571 = 13
Step 5: Subtract 26.571 from both sides to solve for x:
-x = 13 - 26.571
-x = -13.571
Step 6: Multiply both sides of the equation by -1 to isolate x:
x = -1(-13.571)
x = 13.571
Thus, the solution to the system of equations is x = 13.571 and y = 4.42857 (or approximately x = 13.571 and y = 4.429).
