We need to follow PEMDAS

We have to do the addition and subtraction from left to right.

Rearrange the terms

52 - 18 - 34

52 -1(18+34)

52 -1(52)

52 - 52

Answer:

The solution is (-17,80.5) and (1,8.5)

Step-by-step explanation:

Equation 1 : $y=\frac{1}{2}x^2+4x+4$

Equation 2: $y = -4x+12.5$

Substitute the value of y from equation 2 in equation 1

Equation 1 : $y=\frac{1}{2}x^2+4x+4$

After substitution :

$-4x+12.5=\frac{1}{2}x^2+4x+4\\\frac{1}{2}x^2+8x+4-12.5=0\\\frac{1}{2}x^2+8x-8.5=0\\x^2+16x+17=0\\x=-17,2$

Substitute the value of x = -17

y = -4x+12.5

y = -4(-17)+12.5

y=80.5

Substitute the value of x = 1

y = -4(1)+12.5

y=8.5

Hence the solution is (-17,80.5) and (1,8.5)
