What is the largest whole number in the solution set for 6x plus 7 less than 3x plus 10?
6x + 7 < 3x + 106x - 3x
Three times the sum of a number and -7 is 12?
In algebra, this would be how you figure out this equation:3x-7=12+7 +73x=19/3 /3x=19/3x= 6 1/3Therefore, the value of your variable ("x") is 6 and one third.
What is 5X-78X equals 68?
Grouping like terms, -73x = 68 Therefore, 68/-73 = x x = -0.93150684 recurring (that is, -0.9315068493150684...)
What is 11x plus 7 equals 8x plus 19?
11X + 7 = 8X + 19subtract 8X from each side11X - 8X + 7 = 8X - 8X + 193X + 7 = 19subtract 7 from each side3X + 7 - 7 = 19 - 73X = 12divide each sides integer by 3(3/3)X = 12/3X = 4=======Check in original equation11(4) + 7 = 8(4) + 1944 + 7 = 32 + 1951 = 51=========checks
What is the value for x in the following systems of equations x-y equals 5 2x plus y equals 7?
x - y = 52x + y = 7 (use the substitution method)y = x - 52x + y = 7 (substitute x - 5 for y into the second equation)2x + y = 72x + x - 5 = 73x = 12x = 4Thus x = 4 satisfies both the equations of the system.
