The x7 part is multiplication, by the way.

In other words, x = 66/53 = 1.25.

(-15x + 20(7)) = 5+x+3

-105x + 140 = 5+x+3

-106x +132 = 0

-106x = -132

x = 1.24

assuming "x7" is a multiplication sign

here are all the steps for you guys who wonder how i got it so fast

5(-3x + 4) * 7 = 5 + x + 3

5(4 + -3x) * 7 = 5 + x + 3

5 * 7(4 + -3x) = 5 + x + 3

35(4 + -3x) = 5 + x + 3

(4 * 35 + -3x * 35) = 5 + x + 3

(140 + -105x) = 5 + x + 3

140 + -105x = 5 + 3 + x

140 + -105x = 8 + x

140 + -105x = 8 + x

140 + -105x + -1x = 8 + x + -1x

140 + -106x = 8 + x + -1x

140 + -106x = 8 + 0

140 + -106x = 8

140 + -140 + -106x = 8 + -140

0 + -106x = 8 + -140

-106x = 8 + -140

-106x = -132

x = 1.245283019

basic algerbra
