Answer:
1/6
Step-by-step explanation:
To find the value of x that makes the equation true we isolate x on one side of the equation. Technically this is solving for x. The Division Property of Equality states that if we divide both sides of an equation by the same amount then we will have an equivalent equation. We can divide both sides of this equation by 36 to get x = 1/6
Answer: r=7x-1/8
Step-by-step explanation:
2(4r+3)=7x/2+5/2
4r+3=7x+5/2
4r+3-3=7x+5/2 -3
4r=7x+5/2 -3
4r/4= 7x-5/2/4 -3/4
r=7x-1/8
Answer:
√(2 - 7x) + 2x = 0
√(2 - 7x) = - 2x
[√(2 - 7x)]² = (- 2x)²
2 - 7x = 4x²
4x² + 7x - 2 = 0
4x² + 8x - x - 2 = 0
4x(x + 2) - (x + 2) = 0
(4x - 1)(x + 2) = 0
4x - 1 = 0 => 4x = 1 => x₁ = 1/4
x + 2 = 0 => x₂ = - 2
