What is the value of x if 5x - 3 equals 4 - 3x?
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
How do you find value of x of 5x-8?
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
How do you solve the linear system negative 5x plus 3y equals 51 and y equals 10x minus 8 with substitutions?
5x+3y = 51 y = 10x-8 Substituting the bottom equation into the top equation: 5x+3(10x-8) = 51 5x+30x-24 = 51 5x+30x = 51+24 35x = 75 Divide both sides by 35 to find the value of x: x = 75/35 = 15/7 in its lowest terms. Substitute the value of x into the original equations to find the value of y: So: x = 15/7 and y = 94/7
What is the value of the expression 5x plus 12y if x equals 8 and y equals 7?
5x=4012y=84124
7-5x plus 1?
It is: 8-5x simplified
What is the absolue value of 5x plus 8 equals 6?
5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
When x equals 8 what is the value of 5x?
When x equals 8, the value of 5x would be 5 times 8, which is 40.
What is 3x add 7 equals 71 - 5x?
It's a simple linear equation in 'x'.There's only one numerical value of 'x' for which it's true.If you want, you can find that value like this:3x + 7 = 71 - 5xSubtract 7 from each side:3x = 64 - 5xAdd 5x to each side:8x = 64Divide each side by 8:x = 8
What is the answer to 5x - 8 equals 7?
5x - 8 = 7 Add 8 to both sides 5x = 15 Divide both sides by 5 x = 3
How do you solve the inequality 5x plus 8 equals -7?
If 5x + 8 = -7 then x = -3 ! -3 x 5 = -15 -15 + 8 = -7 !
How do you simplify - 3x 8 5x 7?
That depends on the plus or minus values 0f 8, 5x and 7 which have not been given
How do you simplify 5x 8-4x 7?
9x+7
