What is -6y plus 7x equals -9?
It's the equation of a straight-line graph. Every point on the line is a solution of the equation. There are an infinite number of them.
What is -7x plus 10 equals 52?
- 7X + 10 = 52 subtract 10 from each side - 7X + 10 - 10 = 52 - 10 - 7X = 42 divide both sides integers by - 7 (- 7/- 7)X = 42/- 7 X = - 6 --------------------check in original equation - 7(- 6) + 10 = 52 42 + 10 = 52 52 = 52 ----------------checks
What is the ordered pair for 7x-3y equals -52 and 8x plus 74 equals y?
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
What is the equation 7x equals 42?
x=6
How do you solve 4x plus 10 plus 3x equals 52?
x = 6.4x + 10 + 3x = 52We can add the x's together (combine the terms) to get:7x + 10 = 52 (the plus 4x and the plus 3x become plus 7x here).Now we can combine the constants (the numbers) by moving the plus 10 to the same side of the equation as the plus 52. When we move something from one side of an equation to the other we must swap the sign (a plus becomes a negative and a negative becomes a plus). So we get:7x = 52 - 10 (in effect we have actually subtracted 10 from BOTH sides of the equation to keep the equation balanced).Now we simplify:7x = 42x = 42/7x = 6.
