1..) 2x +15 = 35

Masja [62]

Answer:

1) $x=10$

2) $x=3$

Step-by-step explanation:

$2x+15=35$

Subtract 15 from both sides

$2x=20$

Divide both sides by 2

$x=10$

$2(10)+15=35$

$20+15=35$

$35=35$

this shows that 10 is the right answer

$7x-3=18$

Add 3 to both sides

$7x=21$

Divide both sides by 7

$x=3$

$7(3)-3=18$

$21-3=18$

$18=18$

this shows that 3 is the right answer

Hope this helps
