2x plus 2y equals 28 3x plus 3y equals 42?
All that can be deduced is that x + y = 14.
2y plus 3y-7y plus 4 equals 16?
2y+3y-7y+4=16 -2y=12y=-6Check it-12-18+42+4=16-30+46=1616=16
What does '6x-2y' equal when x equals 8 and y equals 3?
the answer is 42
What is the value of y 6y plus 22 equals 4y-42?
y = -32 6y + 22 = 4y - 42 subtract -4y from both sides 2y + 22 = -42 subtract 22 from both sides 2y = -64 Divide both sides by 2 to get y by itself y= -32

Use the Substitution method to solve the system of equationsx plus y equals -4 and x - y equals 2?
x + y = -4x - y = 2x - y = 2x + y - y = 2 + yx = 2 + yx + y = -42 + y + y = -42 + 2y = -42 - 2 + 2y = -4 - 22y = -62y/2 = -6/2y = -3x = 2 + yx = 2 - 3x = -1The solution of the system is (-1, -3)
What plus what equals -84 but multiplies to 1764?
42 and 42
Solve 3x plus 2y equals 0 and -9x plus y equals 42 using substitution method?
3x+2y = 0 -9x+y = 42 => y = 42+9x Substitute the bottom rearranged equation into the top equation: 3x+2(42+9x) = 0 3x+82+18x = 0 21x = -84 Divide both sides by 21 to find the value of x: x = -4 Substitute the value of x into the original equations to find the value of y: So: x = -4 and y = 6
