Question

7x + 2 /4 =18
3 +(y -2) = 2 (y - 1) - 3

solve it please​

Answer 1

Step-by-step explanation:

$7x + \frac{2}{4} = 18 \\ 28x + 2 = 72 \\ 28x = 70 \\ x = \frac{70}{28} = \frac{5}{2}$

$3 + (y - 2) = 2(y - 1) - 3 \\ 1 + y = 2y - 5 \\ y = 6$

Answer 2

Step-by-step explanation:

$7x + \frac{2}{4} = 18 \\ 7x = \frac{18}{1} \times \frac{4}{4} - \frac{2}{4} \\ 7x = \frac{70}{4} \\ 7x = \frac{35}{2} \\ x = \frac{35}{2} \div 7 \\ x = \frac{5}{2}$

2)

3+(y-2) = 2(y-1)-3

3+y-2 = 2y-2-3

-2y+y= -3-2-3

-y = -8

y= 8
