Question

Solve the following .
1) 10=z+3
2) 8x-8=48
3) x/5=12
4) 3x/5=15
​

Answer 1

Answer:

1 z =7

2 x=5

3 x=60

4 X=25 ...........

Answer 2

Answer:

1)

$10 = z + 3 \\ \implies \: z = 10 - 3 \\ \implies \: z \: = 7</p><p></p><p>\: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{ \underline{ Answer }}}$

2)

$8x - 8 = 48 \\ \implies \: 8x = 48 + 8 \\ \implies \: 8x = 56 \: \\ \implies \: x = \frac{56}{8} = 7\: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{ \underline{ Answer }}}$

3)

$\frac{x}{5} = 12 \\ \implies \: x = 12 \times 5 \\ \implies \: x = 60 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{ \underline{ Answer }}}$

4)

$\frac{3x}{5} = 15 \\ \implies \: 3x = 15 \times 5\\ \implies \: 3x = 75 \\ \implies \: x = \frac{75}{3} \\ \implies \: x = 25\boxed{ \boxed{ \underline{ Answer }}}$
