You need to solve this "system of linear equations." In other words, find a point (x,y) that satisfies both 4x-3y=17 and 2x-5y=-11.
Try solution by elimination. Multiply the 2nd equation by -2 to obtain -4x+5y=22. Add this result to the 1st equation. I'd suggest you write this out to see what is happening.
4x-3y=17
-4x+10y=22
----------------
7y=39. Solving for y, we get y=39/7 (a rather awkward fraction).
Now find x. To do this, substitute 39/7 for y in either of the given equations. Solve the resulting equation for x.
Write your solution in the form (x, y): ( ? , 39/7).
Answer is B.
Hope this helps! :)
Answer:
y = 32
Step-by-step explanation:
y = 3x + 5
y = 3(9) + 5
y = 27 + 5
y = 32
Answer:
((1 × 2) + 3) × 4 × 5 + 6 - 7 - 8 + 9 = 100
Step-by-step explanation:
((1 × 2) + 3) × 4 × 5 + 6 - 7 - 8 + 9 = 100
= (2+3) x 4 x 5 + 6 - 7 - 8 + 9
= 5 x 4 x 5 + 6 - 7 - 8 + 9
= 100 + 6 - 7 - 8 + 9
= 115 - 7 - 8
= 115 - 15
= 100
