What is 5x equals 4x plus 7?

If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7


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 8 2x 7-5x?

It is 56-10x


How do you do 24 equals 7x plus 5x?

The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.


Find the slope and the y-intercept of the line -10x plus 2y equals 14?

-10x + 2y = 14 Initial problem (-10x + 2y) + 10x = (14) + 10x add 10x to each side of the equation 2y = 10x + 14 value after the addition (2y)/2 = (10x +14)/2 divide by 2 y = 5x + 7 resultant eqution y = mx + b is the standard form m = 5 and b = 7 via substitution slope of standard formula = m, therefore slope = 5 by definition b is the Y-intercept, therefore Y-intercept is 7 --------------------------------------------------------------------------- Note the Y-intercept is where the line crosses the Y Cartesian coordinate axis at x = 0. therefore it can be calculated as Given y = 5x + 7, and x = 0 then y = 5(0) + 7 y = 0 + 7 y = 7 or in logical terms dialectical analysis Thesis is y = 5x + 7 Antithesis is x = 0 Synthesis is y = 7
