What does y equals -18 equals 9y - 5y plus 10?
4y + 10 = -18 4y = -28 y = -7
What is the solution set of the given equation 4y - 6y plus 9y equals -2?
4y - 6y + 9y = -2Combine like terms on the left side:7y = -2Divide each side by 7:y = -2/7The solution set is: { -2/7 }
8x-7 plus 2x equals 6 plus 5x plus 2?
8x-7 plus 2x equals 6 plus 5x plus 2?
-6x plus 3 equals -7-5x?
-6x+3 = -7-5x 7+3 = 6x-5x 10=x
-7 plus 11x equals 9-5x?
-7+11x = 9-5x 11x+5x = 9+7 16x = 16 x = 1
How do you factor 35x plus 63y?
7(5x + 9y)
What does y equals -18 equals 9y - 5y plus 10?
4y + 10 = -18 4y = -28 y = -7
How do you factor 35x plus 28y?
7(5x + 4y)
Is this equation solvable 3x plus 4y-6c equals -7 and x plus 9y equals 19 and 5x-y equals 3?
YES : Equation (1) 5x - y = 3x + 9y = 19 : Multiply by 5 →Equation (2) 5x + 45y = 95Subtract Equation (1) from Equation (2) to eliminate 'x' terms. This gives : 45y -(-y) = 95 - 3 : 46y = 92 : y = 2Substituting for y in Equation(1) gives : 5x - 2 = 3 : 5x = 3 + 2 = 5 : x = 1Substituting for x and y in the equation 3x + 4y - 6c = -7 gives : 3 + 8 - 6c = -7 : 6c = 11 + 7 = 18 : c = 3
What is the solution set of the given equation 4y - 6y plus 9y equals -2?
4y - 6y + 9y = -2Combine like terms on the left side:7y = -2Divide each side by 7:y = -2/7The solution set is: { -2/7 }
What is 2x plus 3y minus 2 plus3x plus 6y plus 7?
It is an algebraic expression that can be simplified to: 5x+9y+5
What is 5y minus 3 equals 4 plus 9y?
5y - 3 = 4 + 9y Subtract 5y from both sides: -3 = 4 + 4y Subtract 4 from both sides: -7 = 4y Divide both sides by 4: -7/4 = y
What is 5x-9y equals 7 7y-3x equals -5?
If: 5x-9y = 7 and 7y-3x = -5 Then: x = 1/2 or 0.5 and y = -1/2 or -0.5
How do you solve 6x-5y equals 22 and 9y plus 7 equals 5x plus 8?
1. 6x - 5y = 22 2. 5x - 9y = -1 1 times 5: 30x - 25y = 110 2 times 6: 30x - 54y = -6 Subtract : 29y = 116, so y = 4 and x therefore = 7
4y plus 7 less than 3y plus 9?
4y + 7 < 3y + 9 4y - 3y < 9 - 7 y < 2
What is the answer to the problem of the week grade 7 page 43?
