Solve 6x^4-5x^2-4=0
Please include the steps so I can understand

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

An equation in slope-intersept form the lines that passes thought (-8,1) and is perpindicular to the y=2x-17.

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
