because of many reasons boy
Step-by-step explanation:
Given equations:
y = x² + 3x - 29 ------ (i)
y = 2x - 9 ---------------- (ii)
Now to solve this problem, we must determine the value of x and y;
Equate equations 1 and 2;
x² + 3x - 29 = 2x - 9
x² + 3x - 2x - 29 + 9 = 0
x² + x - 20 = 0
x² + 5x - 4x - 20 = 0
x(x + 5 ) - 4(x + 5) = 0
(x - 4) (x+ 5) = 0
x - 4 = 0 or x + 5 = 0
x = 4 or x = -5;
So; solve for y now;
y = 2x - 9
input x = 4 or x = -5;
y = 2(4) - 9 or y = 2(-5) - 9
y = -1 or y = -19

Answer:
X = 105
Step-by-step explanation:
<u>2x</u> = 42
5
Multiply both sides by 5
5 × <u>2x</u> = 5×42
5
5 cancle 5
2x = 5 × 42
2x = 210
Divide both sides by 2
<u>2x</u> = <u>210</u>
2 2
x = 105
