The solution to the given system of equation is -7 and 7
<h3>Solving linear equation</h3>Linear equations are equation that has a leading degree of 1. Given the expression
4x^2 = 196
Divide both sides by 4
4x^2/4 = 196/4
x^2 = 49
Take the square root of both sides
√x^2 = √49
x = √49
x = ±7
Hence the solution to the given system of equation is -7 and 7

Answer:
x = 9
Step-by-step explanation:
A line segment parallel to a side of a triangle and intersecting the other 2 sides divides the 2 sides in proportion, that is
=
=
( cross- multiply )
8(3x - 20) = 56
24x - 160 = 56 ( add 160 to both sides )
24x = 216 ( divide both sides by 24 )
x = 9
