What else can I help you with?
If x equals 3 and y equals 2 then 7x plus 5y equals?
7x + 5y 7(3) + 5(2) 21 + 10 = 31
3 equals 2y plus 7x in standard form?
-7x - 2y = -3
What is the standard form of y equals -7x plus 6?
7x+y=6
How do you solve this using elimination 7x plus 2y equals 10 and -7x plus y equals -16?
7X + 2Y = 10 - 7X + Y = - 16 -----------------------just add 3Y = - 6 Y = - 2 --------------find X, top equation 7X + 2(- 2) = 10 7X - 4 = 10 7X = 14 X = 2 ------------check both original equations for consistency; top first 7(2) + 2(- 2) = 10 14 - 4 = 10 10 = 10 ------------top checks; now check bottom equation - 7(2) - 2 = - 16 -14 - 2 = - 16 - 16 = - 16 ------------------both check and are then consistent
7x plus 2 equals 6x plus 2?
7x + 2 = 6x + 2 if and only x = 0.
7x plus 10 equals 31 x equals?
7x+10=31x so 10=31x-7x or 10 =24x in which case x=10/24 or 5/12
What is 3 plus 3x plus 7x equals 13?
3+3x+7x=13 3x+7x=10 10x=10 x=1
What is the y intercept of y equals 7x plus 10?
The Y intercept of y=7x+10 is 10.
What is 7x - 4 equals 9x plus 10?
7x-4=9x+10-14=2xx=-7
If x equals 10 and y equals 8 then 7x plus 8y equals?
134
What is A equation for -2x plus 8 equals 7x-10?
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
X2 plus 7x plus 10 equals?
The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth
If x equals 7 and y equals 10 then 7x plus 11y equals?
7*7+11*10=159
If x equals 3 and y equals 2 then 7x plus 5y equals?
7x + 5y 7(3) + 5(2) 21 + 10 = 31
What is -10 plus 7x plus 4x equals 78?
It is an equation and the value of x is 8
2x plus 7x minus 10 equals 4x plus 3 minus 2x?
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
What is 7x plus 8 equals 10x minus 2?
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
