Hi! Can anybody help me with these problems? I have to do 2 step equations.

Dovator [93]

1) 3.8x + 5.2x - 6.7 = 11.3
9x = 11.3 + 6.7
9x = 18
x = 18/9
x = 2

2) 7.8y - 4.9 - 5.4y = 2.3
2.4y = 7.2
y = 7.2/2.4
y = 3

3)

$\frac{2}{3} x - 5 = 1$
$\frac{2}{3} x = 5 + 1$
$\frac{2}{3} x = 6$

Multiply by 3 by both sides:

$3 \times \frac{2}{3} x = 3 \times 6$

Simplify:

2x = 18
x = 18/2
x = 9

4)

$\frac{7}{5} y = 3 - \frac{1}{5}$

Do lowest common denominator:

$\frac{7}{5} y = \frac{(5 \times 3) - 1}{5}$
$\frac{7}{5} y = \frac{15 - 1}{5}$
$\frac{7}{5} y = \frac{14}{5}$

Simplify by 5 by both sides:

$7y = 14$
$y = \frac{14}{7}$
$y = 2$
