The value of x in the given quadratic equations is either -2.7 or -11.3.
<h3>What are quadratic equations?</h3>
A quadratic equation is a second-degree algebraic equation in x. ax² + bx + c = 0, where a and b are coefficients, x is the variable, and c is the constant term, is the quadratic equation in its simplest form.
Given first equation, y = x²- 6x + 4 second equation, y = x +1
Put the value of y in the first equation to get
x + 1 = x² - 6x + 4
Solving this equation
x² - 7x + 3 = 0
Using quadratic formula,
x = - b ± 
x = - 7 ± 
x = - 7 ± 4.3
Therefore in the given quadratic equations, the value of x can be either -2.7 or -11.3

No solution.
"G" would have to stand for government spending, so the answer is (a).
139 = x + (2x + 10)
139 = 3x + 10
129 = 3x
