Question

What does x= in each of the questions

Answer 1

Answer:

x+35/5=2

x+35=10

x=-25

Answer 2

Answer:

$\frac{1}{5} x$+7=2, x=-25

$\frac{m}{7} -7=3$, m= 105

$\frac{3}{5} x+7=-20, x= -45$

$-\frac{2}{7} t+5=17, t=-42$

4.9x+4.2=9.1, x=1

Explanation for last two:

$-\frac{2}{7}t+5=17$  

Step 1: Subtract 5 from both sides.

$\frac{-2}{7} t+5-5=17-5$

$\frac{-2}{7} t=12$

Step 2: Multiply both sides by 7/(-2).

$(\frac{7}{-2} )*( \frac{-2}{7}t )= (\frac{7}{-2} )*(12)$

t=−42

4.9x+4.2=9.1

Step 1: Subtract 4.2 from both sides.

4.9x+4.2−4.2=9.1−4.2

4.9x=4.9

Step 2: Divide both sides by 4.9.

$\frac{4.9x}{4.9} \frac{4.9}{4.9}$

x=1
