I would guess it would be
7 and -7
Answer: x = 94.5
Explanation: By using PEMDAS you can see there is no parentheses, exponents, or multiplication, so you start with dividing.
You can go ahead and combine the two x’s so you have 2x. So our equation now looks like:
2x + 2 ÷ 4 = 189
Divide first.
2 ÷ 4 = .5
Subtract from both sides.
.5 - 189.5 = 189
Divide by two to isolate the variable.
2x ÷ 189 = 94.5
so X =94.5
check your answer by plugging in the final number.
94.5 + 94.5 + 2 ÷ 4 = 189.5
