Find two numbers whose sum is -7 and whose difference is 37?
x + y = -7 x - y = 37x = -7-y-7-y-y = 37-7-2y = 37-2y = 44y = -22x - 22 = -7x = 15So -22 and 15
Find two numbers such that the sum of seven times the smaller and twice the larger is 155 and the difference between eight times the smaller and the larger is 3?
Let the smallest number be x, and the larger number be y. So we have:7x + 2y = 1558x - y = 37x + 2y) = 1552(8x - y) = 2(3)7x + 2y = 15516x - 2y = 6(7x + 2y) + (16x - 2y) = 155 + 67x + 16x + 2y - 2y = 155 + 623x = 16123x/23 = 161/23x = 78x - y = 38(7) - y = 356 - y = 356 - 3 - y + y = 3 - 3 + y53 = yThus, the number are 7 and 53.Check:
What is 16-22x-37x?
To simplify the expression (16 - 22x - 37x), first combine the like terms involving (x). This gives us (16 - (22x + 37x)), which simplifies to (16 - 59x). Therefore, the final result is (16 - 59x).
What is four hundred minus what number equals to 37?
400 - x = 37x - 400 = -37x = -37 + 400 = 363
Which best explains why the equation 7x 37x 3 has infinitely many solutions?
The equation (7x + 37x + 3 = 0) simplifies to (44x + 3 = 0), which has a single solution for (x). However, if the equation were presented in a different form, such as (7x + 37x + 3 = 7x + 37x + 3), it represents an identity that holds true for all values of (x), thus having infinitely many solutions. This occurs when both sides of the equation are equivalent regardless of the value of (x).
-3 7x plus 2y?
-37x + 2y you can't add unlike term according to this problem. so it would just be -37x + 2y

How is 3x-5 equals 40-3x plus 3?
3x-5=40x+3 Subtract 3x-5 from each side 0=37x+8 -8=37x x= -8/37
Does 2y squared equals 4y?
Does 2y squared equals 4y? No. 2y² = 2y × 2y 2y² = 4y²
What is 4x-2y plus 3x plus 2y?
4x-2y+3x+2y When simplified: 7x
What is 2y squared times y cubed?
2y squared * y cubed= 2y^5 (2y to the fifth power)
2y plus y-2y?
-2y+y = -y
What is the slop-intercept of -6x equals 2y-120?
-6x = 2y - 120 -2y -2y -2y - 6x = -120 +6x +6x -2y = 6x - 120 -2y/-2 = 6x/-2 - 120/-2 y = -3x + 60
Does 3-2y equal -2y plus 3?
Yes. It is like having a-b, which is a+(-b), which is -b+a, so 3-2y = 3+(-2y) = -2y+3
