Answer 1

Answer:

$10x + 7 = 3x - 28 \\ 10x - 3x = - 28 - 7 \\ 7x = - 35 \\ x = - 35 \div 7 \\ x = - 5$

Answer 2

Step-by-step explanation:

$\huge{\underline{\underline{\boxed{\sf{\pink{✈✄ANSWER࿐}}}}}}$

➡ 10x - 3x + 7 = -28

➡ 7x + 7 = - 28

➡ 7x = - 28 - 7

➡ 7x = - 35

➡ x = - 35 ÷ 7

➡ x = - 5
