7=3(x-1)+4(x-1)

7 = 3 (x - 1) + 4 (x - 1)

x = 2

Solution steps

7 = 3 (x - 1) + 4 (x - 1)

Switch sides

3 (x - 1) + 4 (x - 1) = 7

Add similar elements:

3 (x - 1) + 4 (x - 1) = 7 (x - 1)

7 (x - 1) = 7

Divide both sides by

7

x - 1 = 1

Move

1

to the right side

x = 2

\frac{12 2}{2}

- 12 x^{2} - 35 x - 18

- 2 a - 3 > - 1

85 = 175 t - 16 t^{2}
