An equation to figure out what the answer of "x" is. eg, Removing the brackets - 6(3x-2) = 2(8x+4) 18x-12 = 16x + 8 18x-16x = 8+12 2x = 20 x = 10
It's a linear expression in two unknowns.It can be simplified a little bit:18x + 14y + 3x - 10y = 21x + 4y
3x
It is set for substitution. -3X - 3Y = 3 Y = 5X - 17 ( you have Y given to you, so substitute ) -3X -3(5X - 17) = 3 distribute -3X - 15X + 51 = 3 -18X + 51 = 3 -18X = -48 X = -8/3 Now substitute back into first equation for Y -3(-8/3) - 3Y = 3 8 - 3Y = 3 -3Y = -5 Y = 5/3 You preform the check ( it checks in first equation )
a=b then b=a 3x+5=5 and 8+3x+5 * * * * * The second of these has nothing to do with the question.
