Michael is shopping for clothes. He needs to buy an equal number of shirts and fies. He also needs to buy 4 times as many shirts as pants. Shirts cost $35, ties cost $25, and pants cost $40. If Michael spends S560, how many shirts did he buy?

Michael bought 8 shirts

Step-by-step explanation:

Let the number of shirts to be buy be x

The number of ties too will also be x

The number of pants will be x/4 since he will be buying four times the number of pants for shirts

Amount spent on shirt is 35 * x = $35x

Amount spent on ties = 25 * x = $25x

Amount spent on pants = 40 * x/4 = $10x

Adding all together;

35x + 25x + 10x = 560

70x = 560

x = 560/70

x = 8

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
