x+2x+3x+7x=4x+90

x + 2 x + 3 x + 7 x = 4 x + 90

x = 10

Solution steps

x + 2 x + 3 x + 7 x = 4 x + 90

Add similar elements:

x + 2 x + 3 x + 7 x = 13 x

13 x = 4 x + 90

Move

4 x

to the left side

9 x = 90

Divide both sides by

9

x = 10

\frac{x + 1}{2} = \frac{3}{4}

5 (- 3 + 2 x) = 65

2 (6 - 2 x) + 3 x = 4 + 2 (5 + x)

m^{1}, F = G

5 x + 8 + 3 x + 4 = - 40 + 4
