Solve for y: f(-5)=13+2x
2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9
3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x
2x+3xy-4y=10to solve for yyour objective will be to get y by itself on one side of the equal signyou first subtract 2x to get the terms with y variables on one side3xy-4y=10-2xthen undistribute the y from the two terms to get one yy(3x-4)=10-2xnow divide 3x-4y=(10-2x)/(3x-4)theres your answer
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
show how to solve -2X-4<10 -2X<14 X>-7 (you must change the sign when multiplying or dividing by negatives) Not sure what show steps of how to solve- 10 of 90 means
Solve for y: f(-5)=13+2x
4x=-10 x=-2.5
It's difficult. If you try too hard with this one, you'll zip right past it.-2x - 10 + 4 = 2Combine the -10 and the +4 on the left side :-2x - 6 = 2Add 6 to each side:-2x = 8Divide each side by -2 :x = -4
2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9
4 - 2x = 10 -2x = 10-4 -2x = 6 -x = 3 x = -3
7x=2x-4 5x=-4 x=-4/5
2x - 5 = 15 2x = 20 x = 10
3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x
