Question

1.) 25 - 3x = 88
2.) -11 = 7 - x
3.) 95 = -4 + 33x​

Answer 1

Answer: hope this helps ♡

1.) x = -21

2.) x = 18

3.) x = 3

Explanation:

(minus&minus = plus) (minus&plus = minus) (plus&minus = minus)

1.) 25 - 3x = 88

25 - 25 - 3x = 88 - 25

-3x = 63

-3x ÷ 3 = 63 ÷ 3

-x = 21 → x = -21

2.) -11 = 7 - x

-11 - 7 = 7 -7 -x

-18 = -x

18 = x → x = 18

3.) 95 = -4 + 33x​

95 + 4 = -4 + 4 + 33x

99 = 33x

99 ÷ 33 = 33x ÷ 33

3 = x → x = 3

Answer 2

`\text{1 ] 25 - 3x = 88 }`

`\rm{↣25 - 3x = 88} \\ \rm↣- 3x= 88 - 25 \\ \rm↣- 3x = 63 \\ \rm↣x = \cancel (63)/( - 3) \\ \underline{ \underline{\rm ↣\purple{ \: x = -21 \: }}}`
