Solve by the substitution method 5x plus 3y equals -7 x equals 43 - 8y?
5x + 3y = -7x = 43 - 8y5x + 3y = -75(43 - 8y) + 3y = -7215 - 40y + 3y = -7215 - 37y = -7215 -215 -37y = -7 - 215-37y = -222-37y/-37 = -222/-37y = 6x = 43 - 8yx = 43 - 8(6)x = 43 - 48x = -5Thus, (-5, 6) is the solution of the given system of the linear equations.
What is 4y-7?
4y-7 = -3
What is the slope and y-intercept of 4y - 5 equals 7x?
4y - 5 = 7x ∴y = 7/4x + 5/4 slope = 7/4, or 1.75 4y - 5 = 7x ∴4y/7 - 5/7 = x ∴4y/7 - 5/7 = 0 ∴4y = 5 ∴y = 1.2 the y-intercept is 1.2
Is x 4y 7 a trinomial with a constant term?

4y plus 7 less than 3y plus 9?
4y + 7 < 3y + 9 4y - 3y < 9 - 7 y < 2
Solve for y in the equation 4y plus 7 equals 19?
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
What is the answer to 4y plus 19 equals 7?
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
What is the answer to 7x 7112 4y?
7x+7=112+4y
How do you solve 4x - 4y plus 7 equals 15?
4x - 4y + 7 = 15to get it into y-intercept form do this...4x -4x - 4y + 7 - 7 = 15 - 7 - 4x-4y = 8 - 4x-4y / -4 = (8 / -4) + (-4x / -4)y = x + 2you did not give any values to plug in so this is as best an answer i can give
What is -4y plus 7 equals 35 minus 6?
If: -4y+7 = 35-6 then y = -5.5
What is the slope of -7x-4y equals 16?
To function form. - 7X - 4Y = 16 - 4Y = 7X + 16 Y = - 7/4X - 4 ------------------------ The slope is, - 7/4 --------
What is the answer to 5x - 4y plus 9y plus x -9 plus 7?
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
