7x+30 = 128 -> x = 14
3y+1 = 128 -> y = 42
7x+30
128
3y+1
Move the numbers into the boxes to show the values of x and y.
3y+1 = 128 -> y = 42
7x + 30 = 128
7x = 128 - 30
7x = 98
x = 98 / 7
x = 14
3y + 1 = 128
3y = 128 - 1
3y = 127
y = 127 / 3
y โ 42.33
So the correct values for x and y are:
x = 14
y โ 42.33
