Subtract by 7x and divide by 2.
7x = 21 x = 3
7x + 2 = -4 7x + 2 - 2 = -4 - 2 7x = -6 7x/7 = -6/7 x = -6/7
The answer to the math problem -3 7x plus 7 is x equals 1/3.
It is an equation and the value of x is 2
Subtract by 7x and divide by 2.
7x + 5y 7(3) + 5(2) 21 + 10 = 31
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
X=2
7x = 21 x = 3
-7x - 2y = -3
7x + 2 = -4 7x + 2 - 2 = -4 - 2 7x = -6 7x/7 = -6/7 x = -6/7
The answer to the math problem -3 7x plus 7 is x equals 1/3.
It is an equation and the value of x is 2
x2+7x+12=0 x2+7x=-12 x+Sqaure Root of 7x= 2(SQ Root Symbol)3
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
x2+7x=-2x2+6 3x2+7x-6=0 (3x-2)(x+3)=0 3x-2=0 or x+3=0 x=2/3 or x=-3
