The "answer" usually means the number that 'x' must be in order to
make the statement true. Here's a way to find it:
2 + 3x + 5x = 98
Combine the 'x' terms on the left side:
2 + 8x = 98
Subtract 2 from each side:
8x = 96
Divide each side by 8:
x = 12
98 - 3x = 10x + 20, solve for x.subtract 98 from both sides-3x = 10x - 78subtract 10x from both sides-13x = -78multiply both sides by -113 x = 78divide both sides by 13x = 6
This one looks like No Solution. This is how I read it: 5x = 8 = 98-4x. If 5x = 8, then x = 8/5 = 1 3/5 (or 1.6), substitute into 98 - 4x --> 98 - 4(1.6) = 91.6, which does not equal 8, as it should from the equation.
37 plus 98 equals 135.

98 plus 65 equals 163.
34 + 98 + 98 + 87 + 32 = 349
2 + 98 = 100

given is that 4x+3y=6(3x+3y)=7 i.e., 6(3x+3y)=7 &&& 4x+3y=7 ---------------(1) 3x+3y=7/6 x+y=7/18 _________(2) multiply eqn(2) by 4 4x+4y=28/18 -------------------------(3) (3)-(1) 4x+3y-4x-4y=7-(28/18) y= -98/18 substitute y in eqn(2) x-98/18=7/18 x=7/18+98/18 x=105/18. therefore x=105/18 : y= -98/18
